"I wanted a scripting language that was more
powerful than Perl, and more object-oriented
than Python. That's why I decided to design my
own language."

History
"Often people, especially computer engineers, focus on
the machines. They think, "By doing this, the machine
will run faster. By doing this, the machine will run more
effectively. By doing this, the machine will something
something something." They are focusing on machines.
But in fact we need to focus on humans, on how humans
care about doing programming or operating the
application of the machines. We are the masters. They
are the slaves."
- Matsumoto

Without monster tools like Eclipse it is nearly not
possible to use the language.
